my name is Peter Ivan Dunne,
I am publishing this design as I am unable to raise the funds to build it myself let alone the cost of patents
I believe therefore the best way of ensuring my design is built is to publish it into the public domain
Anybody who wishes to can contact me by email [email protected] using the subject engine

ok for a rotary engine description
this is text only so no drawings sorry

first look at the turbojet engine principle, thanks to nasa we have a basic description here
http://www.grc.nasa.gov/WWW/K-12/airplane/bgp.html simple enough, ok.
to use a jet engine it has to run at an optimal speed to be efficient and powerful, this rotational speed has also to be near
constant and cannot therefore be effectively used in automotive applications.

to get round this problem introduced by the dynamics of a jet engine we need a totally different system,
the solution is to use the screw compressor principle instead of turbines.
a basic description of one can be found at http://www.tpub.com/fireman/102.htm or
http://www.airends.com/LysholmArticle.htm

the advantage of this design is that it can run efficiently over a wide rpm range and when compared to for instance a wankel
design the non-contact design of this device has very low wear and friction

so the basic solution is to replace the intake and exhaust turbines with screw compressors.
theres more to it than that,
take a look at a modern turbo jet, the first turbine is large getting progressively smaller
we can duplicate this effect by designing a screw compressor with a variable pitch so that the screw at the intake end has a
wider and deeper thread width and at the exhaust end shallower and narrower pitch, the exhaust turbines are the opposite as
is our screw compressor.
now we can all look forward to a future with engines enjoying the benefits of simplicity of design, low friction, low vibration and
high fuel efficiency especially when compared to a piston engine

Yes,Yes but what about the electronics ??
